My invention, although applicable to car bonating various beverages, is particularly designed and adapted for csrbonsting beer,

,and in the following description I shell so mention it,-

In carrying out my invention the beer and gas are admitted through concentric pi I cs, that carrying the gas being within the ot ier. The pressure on the beer is very low and '1 at of the gas e little greater, and the pipe supplying the gas is perforated at intcrvels, hence the gas will be injected and partially mixed with the beer before it reaches the body of the nppnrutus. The combined beer nnd gas is injected tangentially into n cylindrical chamber end suitable menus are pro vided therein for churning the mixture. The beer thence passes into and through a. strain ing chamber and into n mixing chamber where it is moved rapidly in opposite directions to complete the mixture and thoroughly incorpointr the gas with the beer:v

The beer is then further strained and con ducted through n pipe to :1 suitable receptacle.

In the device embodying my invention I prefer to arrange the several chambers one above the other, and inject the beer into the lower one and withdrew it from the top of the a ipnratus.

ltcicrr'ing now to the drswings l indicntcs the beer inlet pipe and 2 the gns inlet pipe each connected to a suitable source of supply by the coupling members 3 and 4 respectively. The outer end of the pipe 1 is reduced in diameter as at 5 and the reduced end is provided with an elbow joint 6 upon which is formed the coupling member 3. The elbow 6 is provided with s siniling box 7 through which the pipe 2 extends, the pipe 2 being; arranged wnctnitricslly within t to pipe 1. The pipe 2, between the reduced portion 5 and the body of the nppsrntus, is provided with a plurslity ol small holes 8 which form nozzles through which the gas is inject-ed or sprayed into the beer. The noznles'being in advance oi the rcduced portion 5, the increased pressure due to the injection of gas tends to force the beer l'orwnrdiy into the apparatus inst-mid oi' retarding its passage through the pipe. Si indicates n. support for the pipe. This comprises ft vertical arm 10, preferably formed of pipe, and having a base il by which it is secured to the floor. Upon the upper end oi the pipe 10 is arranged a. chimp for the pipe 1. The clamp comprises a two-part ring .12, the parts oi which are hingcdly connected and provided with the chnnp screw 13.

The pipe 1 is connected to the injecting nozzle 1 by a. coupling 15. The nozzle 14 at its outer end is circular to correspondwith the pipe 1 end the passageway theiethrough is contracted hiterslly as st '16 and flared-or increased vertically, terminating in the narrow v -v disposed dischsr c opening 1?. y 11-: i lprovided with a flange uppers-tile. oi the pipe 2 end is provided in its end with ture or nozzle 19. The opening 17 stsntielly the some width as the pipe 2, hence the beer and gas must pass above and below the some in entering the lower mixing chamber. As the gas is injected laterally from the pipe 2 into the beer contained in the pipe 1, itwill be partially mixed therenitl before entering the body of the apps- The shape of the nozzle 14 tends somewhat to check the free flow of the beer and gas, and it is to counteract this tendency to drive the beer baclnverdly in the supply pipe, as well as for the purpose before mentioned, that the beer pipe is provided with the reduced port-ion r e body the chambers s 2L is secured to the body of the It should be noted that the end extends within the opening 17 a small sperlhe el'ismbei 20 i i ehu no chamber and it is into is th t the inlet diselurrgges, the nozzle 14 being securee to the walls thereof and arranged to dischsrge tangentially,thereinto. The chsmberZl) is defined by the vertically disposed cylindrical member 23 the bottom 2% and the top plate 25. The bottom 24is formed of a circular casting having on annuhir ilenge 26 within which the cylindrical member or shell is soldered. 'lhe member also constitutes the bottom of the apparatus and is supported upon the legs 27.

Mounted within the chamber 20 is s rotary wheel or churn 28. This substmitiolly fills the chamber and is arranged to rotate upon a vertical The churn comprises a central, vertical cylindrical portion 29 of substantially half the diameter of the shell 23, and concentric therewith, the top and bottom plates 30 and 3] respectively, and a plurality oi veins 32. The plates 30 end 31 are circular and extend almost into contact with the wells of the chamber 20, that is the shell and the veins are arranged between the outer portions of the plates which extend beyond the cylinder 29. 'lhe plates close the cylindrical portion of the churn and the veins are solder-ed or otherwise secured to the plates and to the portion 29 forming a plurality of markets 33. The beer is injected tangentially of the chamber into the pockets 33 as shown in Fig. which causes the churn to rapidly rotate, mixing the beer and the gas. The churn is mounted. in bearings 34 and 35 in the plates 24 and 25 respectively, 36 indicating the shaft. The front wall of the chamber is provided with an aperture 37 closed by a glass 38 through which the op- -eration of this portion may be observed.

is sub" reive a rubber gasket 51.

The ormed of two eylindrical ears 39 and f) hingeily connected as at 41. T he member 3?) is slightly larger in diameter than the member 23, but the lower portion thereof is reduced forming :1 depend ing; flange 42 by which it is soldered to the cylinder By reducing: the lower portion of the member 39 a shoulder 43 is formed, flush with the upper end of the member 23 and upon which the plate 25 rests. Slightly above the level of the plate L5 the inner face of the casting 39 is provided with a plurality of lugs 44- through which are threaded set screws These impinge against the upper face of the plate 25ynesr its edge and hold it lirnily in position. 'ihe plate is provided with a plurality of notches 46 in its periphery correspending in number and position to the lugs 44. T he plate may be readily placed in position, the notches passing over or past the lugs after which the plate is turned to bring en. unnotched portion of the periphery beneotlnthe set screws. It should be noted at this point that the notches d6 are suliicien-tly to extend a trifle beyond the inner hire or of the member forming a number of row smell apertures 47, the purpose of which will appear hereinafter.

The member is of substantially equal diameter of the member 39 to which it is hingedly connected as before mentioned. The members 39 and 40 are provided with the peripheral flanges l8 and 49 upon their upper and lower edges respectively. The adjacent feces of the flanges 428 and 49 are provided with the annular grooves 50 to re- The ilmige 48 is provided with plurality of ours or lugs 52 to which are hingedly connected clump screws 5-3. The flange 4,?) is provided with a number of split or bifurcated lugs 52 to receive the screws 53. it is obvious that by loosening the screws 53 and turning them down, the chamber 21 may be opened. The top of the member 40 turns inwardly a short distance as at 54 and is provided with an annular vertically disposed flange 55 to which the shell 56 of the upper chamber 52 is connected, preferably by solder-i mg, the inner edge of the portion 54; being formed with an annular rib 5'7 forming at snoulder upon which the bottom edge of the shell 56 rests.

indicates o/phitc forming u horizontal partition between the cluunbers 21 and 22. This is larger in dimoetcr than the shell and held against the undorfece of the portion 54 by an annular nut 59, the upper end of the member to being thickened and threaded us it 60 to receive said nut. The not 59 comprises a ring the internal diameter of which. is substmitiully equal to that of the chamber :22 and provided with the spider 61 by moons of which it is inserted or removed.

The (luunbr-rs 20 and 21 communicate with curb other through a passageway 62 ex erase"! terioi' of the body portion. To this end the shell 23 and the member 39 are provided with the nipple-s63 and 64 respectively to which are secured the ends of a return bend an aperture 70 in theeonterof the plate 58,

into the upper chamber 22 where it is passed rapidly back and forth through a mixer which I shall designate a shaker and thence through a similar superimposed shaker iinally diseharging into the body portion of the chamberQZ from the top of which it is withdrawn by a pipe 71. Each shaken comprises a plurality of concentric tubes arranged between end plates to which alternate tubes are secured forming a tortuous passageway for the mixture.

Referring now to the drawings '72, 7 3, 74 and 75 indicate a plurality of concentrically arranged and vortieally disposed tubes secured at their lower cnds to the plah 58, the up or face of said plate being provided with the grooved annular ribs 76 into which they are soldered, and each. tube sonmwhai longer than the next adjacent tube, the inner tube being the shortest and the outer tube 75 the longest. The oiiter'tubo 75 is provided with an annular flange 77 at its upper end, the function of whirh will appear hereinafter. 78 indicates a plate or disk resting upon and closing the upper end of the tube 75. From the under face of the plate 7% depeml the eonoentrio tubes 79, Si) and 81' whit-h l(ll scope between the several tubes 72 to 75 forming a tortuous passagx-way for the beer and; gas.

v1n the drawings, the apertures 82 are shown the proper size and the other aper- 62- into the owerehamber.

tures in the plate 78 are illustrated as small as possible to properly illustrate the same. While the latter apertures are perhaps smaller than the apertures 82, this is not an absolute necessity as there are a great number of the apertures 82 and but a small number of the other apertures, perhaps three or four to barb compartment or merely enough to drain the machine when standing inoperative overnight or other considerable lenqth of time. which would pass throu 'h these apertures would make no perceptilile difl'erence in the carbonating. The lengths of the several tubes 83 to 89 are varied similar to those of the lower shaker and for a like pu r )0s". The plate '90 is provided with an annular depending flange 91 on its periphery by means of which it is secured to the outer tube 83 of the upper shaker and the tube 83 is provided with an annular iiange 92 at its lower cdgo between which and the flange 77 tho'outer edge ol' the plate 78 is secured.

The small amount of beer 93 indicate rubber gaskets interposed between the plate 78 and the flanges 77 and 92. The flange 7 7 is provided with a. plurality 'ol' lugs or oars 94 to which are pivotally seeured the clamp screws 95, and the hinge 92 is pro vided with a corresponding number of split or bifurcated lugs 96 to receive said serows.

The tube 89 eXtc-iuls considerably above the plate as at 97 substantially to the top of tho'ehamber 22 and is provided at its upper end with a flange or collar 98 from \Vlllkh extend the radial arms 99.

The carbonated becr rises through the pipe 89 and pusscsout of the upper end thereof beneath the closure lU'l olitho chamber 22, down through the slraincr lllil into the body portion of said chamber from whonre it is drawn oil through the pipe 71. p

102 indicates a small cool: at the upper end ol' the chamber for drawing oil portions of the beer for testing.

ln operating the device it is completely 'lillcd with the beer, all air being excluded, and to this end the 11 )per closure 101 is provided with an air valve 103 to draw (iii the air as the machine is filled.

it is well known that if the beer allowed to stand for any length o'liime it soon beeomes stale, and it is one of the objceis of my invention to provide a machine of tho ebaracler under consideration from which all oi the beer in the machine may be readily withdrawn \Clli n the operation of the nmehinc is stopped. To this end I provide a draw-oil valve 104: in the bottom 24 of the device. it is obvious that the beer in the chambm's 20 and 21 may be readily withdrawn in this manner, that above the level of the opening 67 readily assing through the passageway The vbeer below
